In the Left column is labeled from witch production line the product is.
As you can see the average data from Line 2 is higher as line 1.
It is possible to add more data to sort, Simply add a column and add the labels to sort see below.
As you can see there is no other significant influence. In the graph the operator also looks significant but according the t-test it is not significant.
Be aware with labeling data with more than 1 subgroup (Factor) that has influence on the result the array with the labels easily in
. This is also the case with data in the example (Jan is in 4 data points of Line 1 and only 3 data points of Line 2). So maybe the Operator is significant but due the unbalanced data it is not visible in the result.
When selecting the DOE Graphs it is easier to see the influence of each subgroup.
This is how the sorting looks internally in Develve.
